"Add to homescreen" uses wrong icon
When a website has the same name as an existing icon, "Add to homescreen" will still just use this name for identifying the icon. This makes the system icon instead of the website favicon display on the homescreen.
As an example, adding https://r-a-d.io/ via "Add to homescreen", uses "radio" as the icon name.
